Honestly the trick is you have to want to quit. Not quit because you think you should because you know its bad you just have to want it to be gone.
As for coping tricks, drink lots of water, cut back on alcohol and caffeine, and try and avoid your social triggers that are related to smoking. Maybe dont go out for a bit....
Also accept the reality that you may fail. It took me a heap of times to quit, I would go without smoking for big periods of time (a whole year once) and then start up again until I was finally ready to give them the boot. So if you do have a few smokes dont be too hard on yourself just get back to quitting.
Tell your friends and family that you're trying to quit as well, they will help you and you will feel guilty if you smoke in front of them once you tell them about your plans to stop.
Nicotine patches do help with craving but the reality is its a crutch, just stop, the cravings only last a few minutes, drink some water go for a walk. Plan a day to not smoke and stick to it, remove any smokes from your house, tell your smoker mates not to give you any and try and make it a few days before you get paid (you'll have less cash...) the tips about exercise work to.
Before you know it you'll be fitter, richer and smell way better because as an ex smoker I can tell you that smokers stink. Im sure every ex smoker says it but its really worth the short term pain to quit.
